Brian Whitlock charged with murder

Speaking outside the courthouse, Barbara Whitlock’s widower Warren Clare said he was satisfied with the verdict, but noted the ordeal has been rough on the family.

“That a victim’s family must endure more than two-and-a-half years of turmoil and uncertainty, the mental torture of replaying tragic events over and over, only to have delays and countless adjournments to get to this day.”

With Barbara Whitlock’s two other sons at his side, Clare said the system failed her in her bid to get help for Brian.
